    pseudofs: Don't purge the cache on shutdown
    
    This is a waste of time and results in a use-after-free if linsysfs is
    loaded and a USB network interface is in use, since USB devices are
    disconnected at shutdown, which triggers a call into linsysfs, which
    then tries to destroy a pseudofs node which has already been purged.
